My computer seems to be infected with an AutoConfigUrl hijacker, and after running MalwareBytes, 


the Registry Value - Hijack.AutoConfigURL.PrxySvrRST was found and quarantined. My PC was fine until a restart, where the issue of the proxy slowing down my browser and redirecting my search traffic resumed. Running further scans show no results of threats.


Following some similar cases, I have also located a registry key in HKLM_Software_Microsoft_Windows_CurrentVersion_InternetSettings. 

An AUtoConfigURL with data leading to http://xn--koa.net/proxy.pac.


Trying to change any proxy settings do not take effect, and the proxy configuration is always applied.


Please advise me. Thank you.

That link is definitely malicious. Please do not use your computer to visit Google until it's cleaned up. I would not use that computer to visit anything, frankly, but that link indicates it only wants to steal traffic intended for Google.

Because you're infected and you've tried MBAM, it'll probably be faster to redirect you to the MRT forum. To get help from the MRT (who can use better tools than this section can), make a thread in the Virus, Trojan, Spyware, and Malware Removal Logs section. You have to follow the instructions in the preparation guide prior to posting your thread, since it contains the steps to follow when posting it.

Good luck! :)
